Every user who at least once in his life tried to format some storage medium (hard drive, USB flash drive, etc.) came across such a concept as a file structure or file system.
What is the operating system file structure
Under such a concept as a file structure, first of all, one should understand a certain order of the arrangement of files on any kind of information carrier. Surely, everyone knows for sure that files of different types and sizes can be stored on computers, phones, tablets and other devices. The storage organization determines the format of the information stored in the file, as well as the way it is stored and named. Absolutely all of the above parameters reflect the file structure of operating systems (file system). Each specific file system determines what is inherent only to itself: the size of the name of files or folders, the set of system attributes, as well as the maximum possible size for each attribute. Some file structures of operating systems even allow encryption of stored data, or access control.
File structure characteristics and tasks performed
Absolutely every file structure of operating systems, firstly, names files. Secondly, it creates its own, unique interface for the applications used. Thirdly, it determines the relationship between the logical model and the physical medium. Fourth, it ensures the stability of the system. And, finally, the file structure of operating systems must contain certain information, thanks to which it gets the ability to interact with installed applications, services, services, etc.
File systems are classified among themselves into: oriented random access media (file systems such as: NTFS, FAT32, ext2, etc.), for media with sequential access to information, for network systems, as well as for optical systems, or devices with flash memory. Each of the file systems listed above has its own, unique advantages, has a limitation inherent only in a specific file structure, due to which the uniqueness and security of the operating system used is achieved, and the inaccessibility of access by other users.
Along with all structures that exist in nature, a hierarchical construction model is inherent in the file. This means that in the operating system everything is combined into its own directories, with the help of which the interaction is carried out. Today, all catalogs are combined into their own trees. For example, one of the most understandable for most users = Windows or DOS operating system.
